T0 all whom t may/concern.'

Be it known that I, JOHN ,M,..L1ND1\1A1;, a.. citizen of the United States, residing rvat Seattle, in the county of King and State of Vashington, have invented-certain new and useful Improvements in vVehicle lVheels, ofwhich the following is aspecification,-`

This invention relates` to vehicle wheels of the disk type; and its Vobject is to ,simplify and Aotherwise improve the wheel construction vfor j the purpose of increasing its strength, durability and general eiciency.)v

The -invention consists in the novel construction, adaptation, and combination, of parts vhereinafter ,described and claimed'.

In the drawing,- Figure 1 is a transverse section of a wheel embodying my invention; and Fig. 2 is an elevational view of a partof the wheel with.

l flanges; outside ofthe flanges the disk is curved or bulged laterally, as at 11, and terminates in a peripheral ange 12 which is adapted to furnish a seat for a fixed felly section 14 and aI demountable felly section 15. v

As best shown in Fig. 3, the disk flange 12 is formed to provide two conoidal portions 16 and 17 which taper in opposite directions from a ridge 18 which is disposed circumferentially of the wheel, said tapering portions serving as seats for the respective felly sections. The felly section 14 is formed with a web element 19 disposed at right angles to the wheel axis, or nearly so, and has flange elements 20 Aand 21 extending in opposite directions as shown fromthe inner and outer peripheries, respectivelyof said web element.

The felly flange element 2O is of a conoidal shape corresponding tothe shape of the disk flange portion 16 and to which it is rigidly secured by welding or otherwise.

mountable felly section '.15 is formed to vprovide a yweb element 22 having flange elements4 23afnd 24 extendingfrom its inner and outer vperipheries, respectively.

. The inner flangeof he fellysection 15 is 'y firmly thereupon. ,T he' demountab-le felly which are secured to the web 19of the fixed felly .section and extend through'apertures of. web"22l of the demountable felly section toreceive nuts 26 which engage against the 1 same` :The flanges k21` and" 24 constitute `spaced apart shoulder bearings for Va demountable rim 27 which carries a tire, such as 28 for example.- i y 1 The flanges 21 and 24, moreover, afford lrim bearing seats having outwardly turned rim-retaining flanges 29 and 30.

31 represents a bracket secured as by rivets 32 to the fixed felly section and is provided with an aperture 33 to receive a rim protuberance 34 tov prevent the turning of the rim relatively of the wheel structure.

It is to be noted that the present invention provides a construction employing a disk! flange which is formed with oppositely tapering seats for lboth the fixed and the removable fell sections.

'Ihev outer flanges 21 and 24 of the respective felly sections furnish cylindrical seating surfaces for the rim 27; and the` Abolts 25 `and nuts 26 serve to couple the two fellyV sections together 'and lcause the de# mountable sectionto seat firmly upon the portiony 17 of the disk flange.

What I claim, is,-

f 1. In a disk wheel, a pair of felly members, each having atapering inner peripheral surfaceand a curved outer peripheral surface, a disk having a peripheral flange formed upon its outer circumference with oppositely tapering seating surfaces for the respective felly members, one of saidl felly members being rigidlyV secured to said disk flange, means for removably securing the other of said felly members upon the disk flange, and ar rim adapted to seat upon said curved surfaces of both of the felly members.
